ROCKlNG-CHAI R.

SPECIFICATION forming part of Letters Patent No. 247,656, datedSeptember 27, 1881.

Application filed February 2, 1881. (No model.)

To all whom it may concern:

Be it known that I, EDWARD KETTLER, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and usefulImprovements in Rocking-Chairs; and I do hereby declare the following tohe a full, clear, and exact description of the invention, which willenable others skilled in the art to which it pertains'to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention has as its object the construction of a rockin g-chair in acheap and durable manner, allowing a free rocking motion instead of amovement upon a xed point or pivot or a pendulous movement.

It relates to that class of rockingchairs which have a base frame, uponwhich the upper portion or seat-frame rocks; and it consists,essentially, of a new and improved mode of connecting the base with theseat frame, so as not to interfere with thc free rocking motion of theseat and still secure a firm and durable connection between the two.

In the accompanying drawings, Figure lis a view representing a verticalsection through the middle of the chair from front to back; and Fig. 2 apartial vertical section at right angles to theformer.

A is the frame of the upper portion of the chair, and B the rocker,forming the lower side piece of the seat-frame. This rocker is curved orarched on its lower edge, as shown in Fig. 1, and rests upon thebed-piece c, which forms one of the sides of the base frame or supportfor the chair. I prefer to have theV two meet squarely together, asshown in Fig. 2, but, if preferred, one may be hollowed and the otherrounded on the line ot' the section shown in Fig. 2.

It will thus` be seen from the drawings and my description thus far thatthe seat-frame rocks upon the base with a rolling motion,just as anordinary rocking-chair rocks upon the floor as a base, the point ofsupport or contact between the two moving backward or forward with themotion of the chair.

D is a projecting ear, preferably formed of cast or malleable iron,hrmly attached to the inside of the rocker B by means of the plate g,and provided with a projecting lug, h, and a downwardly-projectingshank, a, in which is a curved slot, b, the form and relativearrangement, as well as the proportion of the various parts, heiligdelineated in the drawings.

A projecting pin, d, is by means of a plate secured to the bed-piece cwithin the slot b, and serves to arrest the mot-ion of the rockerbackward. I prefer to interpose a small block of rubber, cork, or otherelastic substance between the points of contact at C.

To further retainthe parts in position, the l spring E-prelerably madelong and thin and quite broad-is rmly fastened at its two eX- tremities-to the projecting lugs c and h, as shown in Eig. 1. This spring E liesinside the inner edge of bed-piece c, nearly parallel with its upperedge, and while it serves to hold the seat-frame in close contact withthe baseframe it bends readily and permits a free rocking motion in theseat-frame. It should be so placed as to bring the chair intoequilibrium at the position shown in Fig. 1.

It will be-observed that Figs. 1 and 2 show only onehalf the chair, thetwo sides being constructed similarly. y

By the use of the long flat spring greater simplicity and durability isgained, and also a freedom from all rattling and creaking,w'hich arealmost inseparable from the use ot' rubber hands and spiral springs as aconnection.

A great though incidental advantage in my device is found from thisconstruction-admitting the use ot the arched rocker and the rolling, incontradistinction from the pivotal motion ot' the seat-frame.

I am fully aware that rocking-chairs provided with base frames andsupports for the rocking or seat frame have been heretofore employed,and I neither claim them nor an elastic or spring connection between thetwo, broadly.

I am aware that rockingchairs have been mounted upon stationary basesand the two connected by means of springs of various forms andarrangement, and also that rocking-chairs have been provided withslotted arms operating in connection with pins upon the base to limitthe rocking movement of the chair, and I do not claim either of saidfeatures, broadly. I am not aware, however, that any one has hithertoconstructeda single arm in such man- IOO sisting of the curved slottedarm provided with a lateral ange, h, the spring E, provided with meansfor attachment to the chair, and the flanged arm d, provided on itsunder side with a recess, having the cushion C seated therein, 15 saidparts constructed for joint operation, as described and shown.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

EDWARD KETTLER.
